8. Lift differential case assembly out with a suitable tool.

Keep side bearing outer races together with inner race. Do
not mix them up.
Also, keep side bearing adjusting washers together with bear-
ings.
9. Remove side bearing inner race. To prevent damage to bearing, engage puller jaws in groove.
CAUTION:

To prevent damage to the side bearing and drive gear,
place copper plates between these parts and vise.

It is not necessary to remove side bearing inner race
except it is replaced.
10. For proper reinstallation, paint matching mark on one differential case assembly.
CAUTION:
For matching mark, use paint. Do not damage differential
case and drive gear.
11. Remove drive gear mounting bolts.
12. Tap drive gear off differential case assembly with a soft hammer. CAUTION:
Tap evenly all around to keep drive gear from bending.

3. Put matching mark on the end of drive pinion. The matching
mark should be in line with the matching mark A on companion
flange.

cates the maximum vertical runout position.
When replacing companion flange, matching mark is not neces-
sary.
4. Remove companion flange using the suitable puller.
5. Press drive pinion assembly out of gear carrier. CAUTION:
Do not drop drive pinion assembly.
6. Remove front oil seal.
7. Remove side oil seal.
8. Remove pinion front bearing inner race.

INSPECTION AFTER DISASSEMBLY
Clean up the disassembled parts. Then, inspect if the parts are worn or damaged. If so, follow the measures
below.
ADJUSTMENT AND SELECTION OF ADJUSTING WASHERS
Differential Side Gear Clearance

Assemble the differential parts if they are disassembled. Refer to RFD-32, "Differential Assembly" .
1. Place differential case straight up so that side gear to be mea- sured comes upward.
Content Conditions and Measures
Hypoid gear

If the gear teeth do not mesh or line-up correctly, determine the cause and adjust or replace as nec-
essary.

If the gears are worn, cracked, damaged, pitted or chipped (by friction) noticeably, replace with new
drive gear and drive pinion as a set.
Bearing

If any chipped (by friction), pitted, worn, rusted or scratched mark, or unusual noise from the bearing
is observed, replace as a bearing assembly (as a new set).
Side gear and Pinion mate
gear

If any cracks or damage on the surface of the tooth is found, replace.

If any worn or chipped mark on the contact sides of the thrust washer is found, replace.
Side gear thrust washer and
pinion mate thrust washer

If it is chipped (by friction), damaged, or unusually worn, replace.
Oil seal

Whenever disassembled, replace.

If wear, deterioration of adherence (sealing force lips), or damage is detected on the lips, replace
them.
Differential case

If any wear or crack on the contact sides of the differential case is found, replace.
Companion flange

If any chipped mark (about 0.1 mm, 0.004 in) or other damage on the contact sides of the lips of the
companion flange is found, replace.

7. Place the J-34309-11 “R200A” pinion height adapter onto the
gauge plate and tighten it by hand.
CAUTION:
Make sure all machined surfaces are clean.
8. Position the side bearing discs, J-25269-4, and arbor firmly into the side bearing bores. Install the bearing caps and tighten bear-
ing cap mounting bolts to the specified torque. Refer to RFD-16,
"COMPONENTS" .
9. Select the correct standard pinion height adjusting washer thick- ness. Select by using a standard gauge of 3 mm (0.12 in) and
your J-34309-101 feeler gauge. Measure the distance between
the J-34309-11 pinion height adapter including the standard
gauge and the arbor.
10. Write down exact measurement (the value of feeler gauge).
11. Correct the pinion height washer size by referring to the “pinion head number”.
There are two numbers painted on the drive pinion. The first
one refers to the drive pinion and drive gear as a matched
set. This number should be the same as the number on the
drive gear. The second number is the “pinion head height
number”. It refers to the ideal pinion height from standard
for quietest operation. Use the following chart to determine
the correct pinion height washer.

3. Install selected drive pinion height adjusting washer to drive pin-
ion. Press pinion rear bearing inner race to it, using drift.
CAUTION:

Pay attention to the direction of pinion height adjusting
washer. (Assemble as shown in the figure.)

Do not reuse pinion rear bearing inner race.
4. Assemble collapsible spacer to drive pinion. CAUTION:
Do not reuse collapsible spacer.
5. Apply gear oil to pinion rear bearing, and assemble drive pinion into gear carrier.
6. Apply gear oil to pinion front bearing, and assemble pinion front bearing inner race to drive pinion assembly.
CAUTION:
Do not reuse pinion front bearing inner race.
7. Using suitable spacer, press the pinion front bearing inner race to drive pinon as far as drive pinion nut can be tightened.
8. Using the drift, install front oil seal as shown in figure. CAUTION:

Do not reuse oil seal.

When installing, do not incline oil seal.

Apply multi-purpose grease onto oil seal lips, and gear
oil onto the circumference of oil seal.
9. Install companion flange. NOTE:
When reusing drive pinion, align the matching mark of drive pin-
ion with the matching mark A of companion flange, then install
companion flange. Tool number : ST30901000 (J-26010-01)

4. Align the lock pin holes on differential case with shaft, and install
pinion mate shaft.
5. Measure side gear end play. If necessary, select the appropriate side gear thrust washers. Refer to RFD-25, "
Differential Side
Gear Clearance" .
6. Drive a lock pin into pinion mate shaft, using a punch. Make sure lock pin is flush with differential case.
CAUTION:
Do not reuse lock pin.
7. Align the matching mark of differential case with the mark of drive gear, then place drive gear.
8. Apply thread locking sealant into the thread hole of drive gear.

Use Genuine High Strength Thread Locking Sealant or
equivalent. Refer to GI-48, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
CAUTION:
Drive gear back and threaded holes shall be cleaned and
degreased sufficiently.
9. Install drive gear on the mounting bolts, and then tighten to the specified torque. Refer to RFD-16, "
